The newer roof airs use triple starting capacitors on the compressor motor, making them easier to start. They will still draw what older ones do while running, but the triple capacitor design means the surge to start is "softened".
The mach 1 ps model 48257c966 he has dosent come with a start cap, just a run cap, RVP says its not needed
I'm nitpicking here, but this isn't exactly true. See this. The running watts are about 250 higher at the higher temps in the test data.
The locked rotor amps don't change with temperature, which is what affects initial startup. I say "initial" because it may still affect ability to startup if the generator recovery isn't fast enough to keep up with the demand imposed by the higher temp. It "bogs down" for a couple of seconds usually.
The link you gave is PPL`sand is not the newer model mach 1 power saver 48257c966 which is compressor 6.6 @ full load standard condition
fan motor low-2.7 high-2.9 = 9.3 total low 9.5 total high
running watts @ standard condition 1025
running watts @ desert cond. 1260
locked rotor= 41.5
What I said was it dosent have a start cap and it dosent
go to rvcomfort.com and look at the data sheets and the parts lists
signmans AC will run difrently at hotter climate than at 55 degres
but look at the data on the old 9201 cubs
comp amp @ full load standard cond=7.5
fan low =1 amp total=8.5
fan high=1.4 total=8.9
running watts @ standard cond =1000
running watts @ desert cond =1260
locked rotor amps =45.6
the numbers for locked rotor are lower on the mach
and very close on watts
It should run very simalarly to the old cub , the tests are done by the same company after all
No reason to not belive the numbers
